blueman-applet crashed with UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8e in position 4: invalid start byte

Status changed to 'Confirmed' because the bug affects multiple users.

Error appeared during latest set of package updates.

after update .. not rebooted

I keep having this issue. I'll try to make a debdiff and see what I can do.

Actually, it seems like this is fine now, maybe in version 2.1.2. I don't see any issues now...

A lot has been updated since Ubuntu Cinnamon (which is what I'm testing on) Beta ISO has been released and a rebuild will begin on Wednesday at 7 PM EDT. Then I can see where we are. So lets hold it for now.

Just happened to me. Running 20.04 with blueman 2.1.2-1

I had left the system up and running with Chrome browser open for a couple of hours. When I came back the notice of failure was one the screen.
blueman/focal,now 2.1.2-1 amd64 [installed,automatic]

Same here with 2.1.2-1 amd64 at UbuntuStudio 20.04 beta. Updated with proposed packages few minutes ago, but not rebooted because it is a live usb.

I still can't find it, but I think it's safe to say that it's time to contact the maintainer about the issue-continuously, this is clearly a problem.

I contacted the maintainer, awaiting response. I built an Ubuntu Cinnamon-Remix ISO just now with the fixed update-manager patch and the bug crash report doesn't appear. Make sure you upgrade your blueman, and then see if it persists through different products.

this crash happened to me on a fresh install of focal while doing the first software update.

Blueman-applet was running in the panel and apparently is running again after the crash ..

I just tested and played with my Ubuntu Cinnamon Remix for Apr 16 (Final Freeze), and I see no issues with blueman at all. I suggest a close

This just happened to me. I just upgraded a couple of days ago to Ubuntu 20.04

Confirmed here as well. Just did a fresh re-install of ubuntu studio 20.04, this is happening out of the box. This is with Sengled bluetooh speaker/LED lights. I should note, audio connects and works with no issues. This happens when trying to bind to the bulb's serial port (to contol dimming). Worked fine on 19.10.

Running Ubuntu MATE 20.10 I had the blueman-applet crash. First time having the crash in 20.10

Safe to say its time to backport a patch from upstream if it exists

wait-this issue still occurs and yet we still use python2 here?

Checking https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=942916, in version 2.1.3-2 they switch to cython3.

Three releases occured since 20.04 release. And in JournalErrors, too, systemd has had issues, which was also patched in latest versions of blueman.

Updates are relatively sparce sadly-but it's worth SRUing all the patches we did to 20.04 to quickly fix this thanks to Eoan support ending.

Reproduced on Ubuntu 20.04 when using my Sony WH-1000XM3 headsets

Reproduced on Ubuntu 20.04. The error message appears starting or stopping the bluetooth service ("sudo systemctl start bluetooth.service" or ""sudo systemctl stop bluetooth.service"").

same here. Thanks

This is occurring 21.04 after upgrades on 10 Nov. 2020

For me it occurs on 20.10 with updates from a few days ago while pairing my Thinkpad Bluetooth Laser Mouse. Other devices are working fine.

This error was annoying. Something triggered it and the logs were not clear on what.
I'm was file corruption somewhere. I had some old files in /home/myusername/.cache/blueman*
I removed those and logged out and in. No more crash but it may not last.

Just happened to me in jammy when changing some sound configuration via "Pulseaudio volume control" while listening to music via bluetooth headphones. After the crash, the bluetooth connection had broken and audio came out of the internal speaker instead.

I just had the same happen to me in 23.04 / Lunar Lobster. Also sent in a crash report I hope. No idea when or if anything iin particular was happening; just got the crash report pop up after having to force a reboot.

Just happened in 22.04, when using bluetooth for EasyTether.

Running Ubuntu 22.04.2 LTS.

Architecture, according to bug report (presumably Apport 2.20.11-0ubuntu82.5): amd64.
But the processor is intel vPRO i7, and "uname -m" reports x86_64.
